Abstract
The present investigation was carried out at the Department of Horticulture, G.K.V.K., U.A.S., Bengaluru, to study the effect of different levels of application of microbial media amendment on growth, yield and quality of Gerbera cut flower. The microbial media amendment (Mycoplex) was applied to the soil at the rate of 30 g/m2 and 50 g/m2 along with the recommended dose of fertilizers, at the intervals of 30 days and 60 days after
planting. It was observed that plants grown in the treatment T3 (Mycoplex: 30 g/m2 of bed as basal dose + 75% recommended dose of fertilizers) showed highest growth in terms of maximum plant height, number of leaves per plant, leaf area and number of suckers per
plant. The treatment T3 also proved to be useful in early flowering (reducing the number of days taken for flower bud initiation) and time taken for bud to bloom was also found to be reduced. During a period of 270 days, maximum number of flowers per plant, flowers per m2 and flowers per hectare ware recorded in T4 (Mycoplex: 50 g/m2 of bed as basal dose + 75% recommended dose of fertilizers), where as maximum stalk length, flower diameter and vase life were obtained in the treatment T3 (Mycoplex: 30 g/m2 of bed as basal dose + 75% recommended dose of fertilizers).
